Buffer Overflows
A buffer overflow occurs when an attacker sends more information than a program is designed to handle, or when poor programming allows extra data elements to overflow in a computer program. The overflow may corrupt other nearby programs or may contain code directing the computer to take destructive actions. When the program is overwhelmed, it often simply opens the system. This can give an intruder root privilege, depending on the program. Root privilege means complete and absolute control of the system. Buffer overflows commonly provide an open door to intruders.
